Million guide is "highly accurate, highly rigid & of no rotation" owing to its simple mechanism using needle rollers.


Point to line
"Ball to needle roller", Million guide adopts needle rollers as rolling
element and realizes highly accurate linear motion.
This is the "ultimate form of linear guide".

5.Counter marks

Set the counter marks of the bush (bottom side) and the post flange (side face) at the same rotational position. You cannot use the Million guide under the condition that the counter marks does not meet, since the final finish is made with the counter marks at the same position.


6.Serial No.

The original serial numbers are carved on the post and the bush. The Million guide is controlled and manufactured at the pair of the post and the bush, so you cannot use it with the different serial numbers. Check the serial number combination before usage.

Features

1.Point to line contact

High rigidity by line contact.

1.Point to line contact

2.Low pre-load

Smooth motion by low pre-load

2.Low pre-load

Higher pre-load (5-12µm) for keeping the rigidity on the ball guide brings impact/ vibration at the entry, leading to shorter product life.   Lower pre-load (2-6mm) for the roller with high rigidity brings smaller impact and smooth motion at the entry, leading to longer product life.

High accuracy by adding a few µm pre-load on the roller for the tight fitting.


3.The needle rollers are arranged in polygonal position.

Hexagonal structure can stop the rotation.

3.The needle rollers are arranged in polygonal position.

There are no stoppers for rotation.   No rotation by the needle rollers in polygonal position.

How to install the positioning attachment

How to install the positioning attachment - Push

As the left figure shows, the positioning attachment to the post flange part makes the post positioning and leads to easy re-installation of the post.
<Notes>
  • Select the post length so that the post keeps the bush at the top dead center during the press process.
  • Use it with the stroke where the needle rollers make one revolution or more if possible.
  • Million guide is a pair of the bush and the post. Check the serial numbers before installation.
  • Make sure there is no rotational moment between the post and the bush at installation.
  • Design so that the retainer does not come out from the bush during operation.
  • Million guide cannot be used without any lubrication. Therefore regular lubrication is required.
  • Use the dust proof boot on Million guide to protect the sliding area in dusty environment.
  • Use the Million guide 0-105°C environment.
  • Choose U Polymer for retainer material in case of using at 65℃ or higher temperature environment.
  • Do not modify the Million guide. (may affect the accuracy and specification)

Million guide lubrication

Million guide cannot be used without lubrication; Regular lubrication is necessary. In case Million guide is not properly lubricated, premature wear may occur, leading to the performance degradation. Lubricate the Million guide properly with reference to the followings.

1.Recommended lube
We recommend oil lubrication under the environment where oil is usable. In case oil is unusable, lubricate with grease.
<Oil lubrication>
  • (For normal use: feed speed 100m/min or less) Bearing oil/Turbine oil ISO VG46
    <Isel/Million oil M046(Coming soon) recommended>
  • (For high speed use: feed speed 100m/min or less) Bearing oil/Turbine oil ISO VG32
    <Isel/Million oil M032(Coming soon) recommended>
  • (For heavy load use) Bearing oil/Turbine oil ISO VG68
    <Isel/Million oil M068(Coming soon) recommended>
<Grease lubrication>
  • (For normal use): Urea extreme-pressure grease
    <Isel/Million grease MGS (Refer to P33) recommended>
(*)We also provide grease for clean room and vacuum. Please contact us.
2.Lubrication method
<Oil lubrication>

Lubricate with oiler or spray etc. at the proper points according to the installation posture so that oil reaches every part of needle rollers.

<Grease lubrication>

Apply grease directly to the needle rollers of the retainer if possible. If direct application to the needle roller is difficult, apply thinly to the sliding part of the post or the bush. Application during stroke makes good lubrication. Be careful not to apply excessively because the excessive amount of application may cause heat generation and sliding resistance increase for both cases.

3.Others

We also provide special ordered Million guide of the lubrication specification shown at the right figure. Please contact us for other methods.
